Directions: The item consists of two statements, one labelled as the ‘Assertion (A)’ and the other as ‘Reason (R)’.You are to examine these two statements carefully and select the answers to the item using the codes given below:Assertion (A): In microwave communication links, intensive fading at 18 GHz band occurs due to rain-drop attenuation.Reason (R): Collective scattering from water droplets in the atmosphere will result in diminution of energy in the forward path and this is maximumat the 18 GHz band because the criterion for scattering are more satisfied by the wavelength dimensions at these frequencies.

• A. Both A and R individually true and R is the correct explanation of A
• B. Both A and R are individually true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true
